SPHG'N-VALVE EOE FLUSHIllG-TANKS.

To all whom it' may concern.'

lle it known that l., tloi-1N J. MEYER, a itizen ot the United States, and a resident of l'vonkersv in the county of Westchester und State'ot New York, have invented a new and Improved Siphon-Valve for Flushing- Tnnks, of which the following is a full, clear, and exact description.

The invention relates to discharge valves ot flushing tanks for Water closets, urinals, and other similar i'ixtures, and the object of the invention is to provide a new and improved siphon. valve which' is sin ple and dun ralile in construction and arranged to perinit a full or only a partial discharge ot' the water vin the tank troni above the normal level of the Water in the tank; to provide means for the escape of overflowing water from leakage of valve cocks; and to prevent Waste oit' Water by leakage or other causes. For the purposes mentioned use is made of e siphon and e manually controlled start-ing device for the Siphon, and having a cylinder and a plunger movable therein; and a nor -ially open valve adapted to close on lifting the plunger so that the latter raises the Water to' the upper end ot' the long leg ot the Siphon to start the saine. ilse also made ot en air vent passage in the stein of the plunger for connecting the atmosphere with the siphonto break the siplioning actionv thereof and manuel y operated means on the said stein for controlling the saidl air vent passage.

A practical embodiment of the invention is represented in the accompanying drawings forming part of this specilication, in 'which similar characters of reference indi cate corresponding parts in all the views Figure l a sectional side elevation or" the siphon valve es applied; Fig, 2 is a cross section of part of the saine on the line 2 2 of Fig. l; Fig. 3 is a like View of a modified form of the saine; Fig. fl is a side elevation partly in. section of a modified form of the siplron valve as applied; Fig. 5 is an enlsrged sectional side elevation of the valved inlet for the short leg of the Siphon shown in Fig. 4; Fig. 6 is a' sectional side elevation ot' a modified form of plunger stem and normally open valve; Fig. 7 is a similar view of another modified forni of the same; and

Fig. 8 is a sectional side elevation oie, modi.- tied tornlof the normally open valve.

, rlhe Siphon illustrated in Fig. l consists of a long leg and a short leg E of which Specification of Letters Patent.

the lower end of the long leg A is screwed or otherwise secured iu a thimhle C att-ached to the loototm l) ot' a flushing tank D1 by the use of a nut G1 screwing on the lower end of the thiinble C againstthe under side of the bottoni l). To the extreme lower end of the t-hiinble C is coupled the 'flushing pipe Eby the .use of a suitable coupling E1, it being understood that the said liushing pipe leads to the Water closet, urinal or other {iX- ture to be iushed. lThe .lower end of the short leg B is connected with the upper end ol a cylinder l?, preferably in the form ot' a bell having a closed top F1 and an open outwardly flaring lower end F2, provided in the side Walls With a series oi graduated openings F3 for gradually venting the lower end of the cylinder at the time the level of the water in the tank D reaches the said openings F3. el. plunger G is mounted to inove up and down in the cylinder F, and the said plunger is raised hy the use of a stein H passing centrally through the plunger G and carrying at its lower end a collar H ,adapted plui'iger (l. The stein H extends through a hushingor hearing l held on the top .F1 of the cylinder F, and the upper outer end of .the stein El is provided with a head H2 conuected by a flexible link, or other link, with an actuating mechanism under the control ot the operator for raising the stem H and with it the plunger G so as to lift the water in the cylinder F to start. the Siphon action and thus Wholly or partly empty the tank D of its contents hy Way of the short leg B and the long leg A, es hereinafter more fully described. v

The plunger G is provided with one or more openings G1 adapted to loe closed by a normally open valve K having a limited sliding movement on the hub G2 of the plunger G, the seid huh being provided at its upper end with a hea-d GB against which butts t e normally open valve K so as to leave the openings G1 unohstruetedor thepassege of water to the top of the plunger (l. The head G3 is provided with an annular recess Gt and with notches G5 in the side wall, and the said recess G4 is adapted to register with an opening HS ormedin the Wall of th@ stern ll and leading to an air vent passa e l-lf having en opening H5 in the head l, so that air can pass by Way of the said air vent passage into the recess G4 and by Way of the notches G5 into the upper end of the to engage the under side of the y cylinder F to break the siphon whenever the parts are in the posit-ion shown in Fig. 1, that is, when the stem H is in lowermost po sition and the plunger G is in uppermost position. The opening H5 of the air vent passage H4 is 'controlled by a screw plug Hi screwing in the head H1 and under the oontrol of the operator to control the amount of air passing into the air vent passage or to permit of completely closing the entrance opening H5 of the said air vent passage.

Instead of providing 'the head G3 with notches G5 for the passage of the air into the upper end of the cylinder F, use may be made of a recess F 4in the under side of the top F1 (see Fig. 3) to allow the air to pass from the recess G4 by way of the recess F4 into the upper end of the cylinder F.

The operation is as follows: When the plunger G is in the lowerinost position, as shown in dotted lines in Fig. l., and the valve K is in itsI normal position and the stem H4 is raised, then the pressure of the water against the top ofy the valve K moves the latter downwardinto engagementv with the plunger G, thus closing the openings G1. The water in the upper portion of the cylinder F is now lifted by the plunger G and the closed valve K and forced up through the short leg B into the long leg A to start the Siphon, it being understood that as soon as the plunger G reaches its uppermost position shown in Fig. 1, then the valve K iininediatcly arises and uncovers the 'openings G1 to allow the water to flow through the said openings G1 to maintain the siphoning action. .As long as the operator holds the stem H in a raised position the siphoning action will continue, but as soon as the operator lowers th'e stein H then atmospheric aii passes by way of the air vent passage H4 into the upperlend of the cylinder F so that the siphoning action is broken and the water lowers in the cylinder F to the level of the water in the tank D1. In case the opening H11 of the air vent passage H1 is closed by the screw plug H, then the siphoning action is not broken until the water in the tank .D1 roaches the openings F 3, and consequently the tank D1 is almost completely emptied of the water contained therein. It isunderstood that when the plunger G is raised and the siphoning action is started, then the flow of the water from thel cylinder' F into the siphon holds the plunger G in uppermost position as long as the siphoning action continues, but when the siplioning action is broken on lowering t-lie stem H, then the plunger G and with it the valve K move downward with the receding water ,in the cylinder F, and the plunger G finally drops Vinto its lowerniost position on the collar H1.

When the screw plug H6 closes the opening H5 then the lowering of the stem H does not break the siphoning action, and consequently the tank D1 is emptied of its contents whether It is usually connected to the ball cock,out-

let if desired to refill' the pool of water in toilet below. The lower end of the long leg A may be provided withV a screw, which when removed permits draining of the water out of the tank D1, and if set loosely will allow' water to trickle down to compensate forA Water evaporating in trap outlet and moistening washer when not used frequently. Y

It is understood that the height of water in the tank can be determined and regulated by the usual apparatus illing the tank, ,so that the water level can be below, even .with or above the air vent inlet H5 on the stem; orv liic stem can be lengthened if desired to locate the inlet H5 above the watervlevel; when the stem is in its lowermost position the vent passageH4 and openings H3, 'H1 form an auxiliary overflow provided the vent opening H5 is open and other valve ar-4 rangements are out of order.

In the modified formshown in Figs. 4 and 5 the long leg A1 of thesiphon is attached to the bottom D of the tank D1 in the same manner as above described relative to the long arm A, and the short leg B1 in this case extends to within a short distance of the bottoni D1, and the said short leg B1 is connected near its upper end by a pipe P with the upper end of a cylinder F1 reaching with its lower opening within a short distance of the bottom D. In the cylinder F1 moves a plunger Gs'held on the `stem H1, provided at its upper end with a head HS connected with 4the operating mechanism for raising or lowering the plunger G6 in the cylinder F1 to lift water into the siplion with-a view to start the siphoning action thereof. In order to prevent the lift of water from flowing outfroni the short leg B1 the lower end B1 thereof is provided in its bottom with an opening B3 adapted to be closed'by a normally open valve K1 having a stem K? mounted to slide loosely in a bearing B4 forming part of the short leg B1. (See Fig. 5.) lVhen the water is lifted'by the plunger G11 into the short leg B1 the pressure of the water moves the valve K1 into closedposition until the siphoning action is started and the plunger G6 is at rest so that the valve K1 moves back into its normal open position, thus allowing the water to flow from the tank D1 through the opening Binto the short leg B1.. The upper end ofthe cylinderF' is provided at one Side With a by-pass F reached by .the plunger G at a time the latter moves into uppermost position, so that water from the lower portion of the cylinder F"I can pass by way of the said by-passiF'into the upper end of the cylinder 5 and by way of the pipe P to the short leg B1.

The normally open valve K may be of various constructions. For instance, as Shown in Figs. l and 5 the valves K and `K1 are each in the form of a hollow body suiliciently light to move upward intoI open position when immersed 1n water. The

normally open valve P shown in Fig. 6 isv 1 Fig. 7 are in the form of hollow flat valves pivotedon the top of a plunger T providedA with openings T1 adapted to be closed by the said valves S whenever the plunger '.lr

is raised, as previously explained. The plungcr'T is providedl with a hub T2 having a head T3, and the plungerAv is engaged by a stem U provided at its lower end with a lcollar U2 engaging the under4 side of the plunger T.

'. The normally open valve V shown in Fig.

' 8 consists of aninverted cup-shaped shellA V1 filled with cork V2 Aor other similar light material, the cork being fastened to the is'hell by suitable fastening devices V3, such A as clips,screws. or the like.

.l It .is understoodthat the valves K, K,

QP, ,S and V are normally open when imf mer'sed in water-,that is, the valves owing to utheir buoyancy are normally open under water. It is also understood that the novvelty of the important function of the nor- 'mally open valve is to allow the escape of accidental accumulations of `water in the tank, to prevent water flowing over the top of the tank in case the lever or chain Should cause' the plunger to stick half way in the cylinder when the other outlets would not allow water access over plunger. It is fur- `ther understood that when siphonage is than the water. The float K while raising itself to its limited position will not raise the plunger. "When the plunger G is in its wardly-curved portion F2 of the cylinder F so that suliicient space is had between the edge of the plunger G and the said curved portion for the passage of water from the tank D1 into the cylinder F, and hencean auxiliary overflow is provided.
